ABSTRACTStandardization of herbal formulation is essential in order to check quality, purity, safety and efficacy of drug. “Swadisht Virechan” churna play an important role in constipation and detoxification due to safety and efficacy in it. Hence churna has been formulated by standard procedure and evaluated by organoleptic study, physical characteristics and physicochemical screening. One marketed formulation and one lab scale formulation were subjected to comparative standardization. The churna was standardized by determination of organoleptic characters, pH, loss on drying, ash value, extractive value, physical characteristics such as bulk density; tap density, angle of repose to determine flowability, determination of particle size, microbial content. The result of various parameters obtained from study showed that marketed formulation and lab scale formulation have comparable physical values. The flowability of formulation was found to be poor in both formulations. These studies showed that there is no uniformity in preparation of formulation which is may be due to varied geographical locations where there plants grow. The present paper reports the investigation and standardization of swadisht virechan churna an Ayurvedic formulation. The physical parameter evaluated confirms the standard of the formulated churna.
